This rocket started at rest on the lunch pad. At a certain point in the time, WATER with a mass of 2 kg was coming out of the rocket with velocity of 10 m/s. If the ROCKET has a mass of 5 kg, what is the velocity of the rocket?

A - 20 m/s
B -0.25 m/s
C 1000 m/s
D 4 m/s

Infrared radiation has wavelengths that are shorter than visible light is part of the visible light spectrum has wavelengths that are longer than visible light has the same wavelengths as ultraviolet radiation

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.

6–48 bananas are to be cooled from 24 to 138c at a rate of 215 kg/h by a refrigeration system. the power input to the refrigerator is 1.4 kw. determine the rate of cooling, in kj/ min, and the cop of the refrigerator. the specific heat of banana above freezing is 3.35 kj/kg·8c.
